The DVU2120 is a pneumatically controlled dump valve. The valves open and close automatically by pneumatic control from a Murphy LS200NDVOR or similar level controller and dump valve operator. Diaphragm operated, the DVU2120 dump valves operate at 30-70 psi (207- 483 kPa) [2.07- 4.83 bar] and up to 2000 psi (13.8 MPa) [138 bar].

Designed for gas compressor scrubbers, the DVU2120 can be used to dump any liquids compatible with its specifications. A key benefit of this design is a hex union that provides the ability to replace the seat without removing the valve from piping.
